A MEASUREMENT OF THE NEUTRAL HYDROGEN DENSITY DETERMINED FROM BALMER ALPHA FLUORESCENCE SCATTERING IN THE HBTX1A REVERSE FIELD PINCH

Abstract

The determination of the neutral hydrogen density in a reverse field pinch using a Balmer alpha fluorescence scattering measurement is described. A large discrepancy is found between the experimental results and those predicted by a time dependent collisional - radiative model. Possible implications are discussed.
